Really worried..

I’m almost 5 days late for my period. This is very strange for me because I’m always regular. I get my periods at the end of the month so usually around the 27th. My periods last for about 3-5 days. I’m a really stressed out person I’ve always have been and I know stress can hold off a period but it’s never happened before.

Well this month is different I’ve had really bad cramps and back pain but no bleeding not even any spotting just thick creamy CM. I’ve taken about 5 tests everyday and they all come back negative. BFN’s. It’s all so confusing I don’t know what’s wrong with me. I’m booking an appointment tomorrow morning to see my doctor I just hope it’s nothing serious. I just wanted to know if any other ladies are in the same boat as me or have been before. Crossing my fingers it’s nothing serious! ☹️🤞🏻
